" Aaiiaisttetrary 10, 1950, Serial No. 143,542 I This invention relates to. cleaning devices such as dish mops, floor mops and toilet cleaners in which a mass of cleaning, scrubbing orwiping material is secured to oneend of vairigid stick or handle; Such devices. are commonly used with water containing a soap orsome detergent-agent in solution.

It is the general object of my invention to provide a cleaning device which includes a selfcontained means for supplying a portion of such a cleansing agent in liquid form while the device is in use. I also provide improved means for dispensing such a liquid cleansing agent, preferably by simple pressure of the stick or handle against some fixed surface, such as the bottom of a pan or pail.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention as embodied in a dish mop is shown in the drawings, in which:

Fig. l is a sectional side elevation of a dish mop, partially broken away to show interior structure;

Fig. 2 is an enlarged partial side elevation of the dispensing end of the dish mop; and

Figs. 3 and 4 are detail views, IOOkiIlg in the directions of the arrows 3 and 4 in Fig. 2.

Referring to the drawings, I have shown a dish mop comprising a handle H! in the form of a hollow tube, which is preferably of a rigid transparent plastic material.

A collar 12 may be cemented or otherwise secured to the outside of the tube l near one end thereof, and a mop M may be secured to theend of the tube In in any convenient manner, as by looping the component threads T about a ring l4 disposed at one side of the collar I2, and by confining the threads T by a ring H5 at the opposite side of the collar 12.

'The details of construction of the mop and its attachment form no part of my present invention.

A valve V is mounted in the right-hand end of the tube It] (as viewed in Fig. 1) and is shown in enlarged detail in Fig. 2. A double-beveled sleeve 20 is secured in the end of the tube and projects outward therefrom. A valve memher 22 is slidably mounted in the tube l0 and has a conical face 23 adapted to seat against the beveled inner end 24 of the sleeve 20.

The inner end portion 26 of the valve V is freely slidable in the tube [0 and acts as a guide 25 is preferably provided with a plurality of, notches 28 (Fig. 4) to permit the cleansing liquid to pass freely by the valve member 22 when the valve'is open.

The valve member.

ahead 32. The stem 30 has a plurality of radiatin vanes 34 fixed thereto and freely slidable in the sleeve 20. These vanes provide additional guiding surfaces.

The sleeve 29 has a shoulder 36 to receive one end of a spring 40 which encircles the plunger 30 and has its outer end seated in a recess 42 in the inner side of the head 32. The inner face 44 of the head 32 is preferably beveled to correspond to the bevel of the adjacent end 45 of the sleeve 20.

The outer end of the sleeve 20 is preferably notched as indicated at 50 (Fig. 3) to provide a clear path for the liquid when the valve is opened and when the head 32 is pressed against the end 45 of the sleeve 20. A plug is removably mounted in the left-hand end of the tube I0.

When the device is to be used, the plug 55 is removed and the tube I0 is filled to any desired extent with liquid soap or with any other liquid detergent or cleansing material. The plug 55 is then reinserted and the liquid material will be stored in the tube It) until desired for use.

If the mop is then pressed against a fixed surface, such as the bottom of a pan or pail, the valve V will be pushed inward and will be thus opened, and a portion of the liquid cleansing agent will flow through the valve and into the water in the pan or other container which is in use in the cleaning operation. As soon as pressure is removed, the valve is automatically closed and prevents further escape of the liquid agent.

A small hole 10 may be provided in the plug 55 to vent the tube ll].

As the valve V is pushed inward, the valve surfaces 26 and the vanes 34 guide and center the valve and prevent binding thereof, and the beveled surface 44 of the head 32 also acts to center the valve as it is seated against the beveled surface 45 of the sleeve 20. This latter action is particularly desirable where the pressure on the head 32 is in part transverse instead of axial.

A cleaning device constructed as above described has been found very convenient and useful and makes it possible to supply any desired proportion of soap or other cleansing agent without interrupting the dish washing, mopping or for the inner end of the'valve. The end portion is other cleaning process.

22 has a stem 30 extending; outward through" the sleeve 20 and provided with Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:

A dispensing device for a liquid comprising an elongated hollow cylindrical container for said liquid, a sleeve secured in and projecting partially from one end of said container and having oppositely-beveled inner and outer end surfaces and having an outwardly-facing intemal shoulder, a valve member slidable in said container and sleeve and having inner and outer enlarged ends, a reduced connecting portion and a plurality of guiding vanes thereon, the inner end of said valve member having a short cylin drical portion loosely slidable in said container,

said cylindrical portion having a plurality of longitudinal grooves about its periphery to allow flow of liquid past the inner end of said valve member when the valve is open, and said valve member having a frusto-conical portion seated 20 Number against the outer beveled end of said sleeve when the valve is open, and said sleeve havin a plurality of end notches extending above the beveled outer end surface of said sleeve and providing radial passages for liquid when the valve is fully open and when the frusto-conical inner surface of the outer end of the valve member is seated against the beveled end surface of the sleeve, and a spring compressed between the in- 10 terna'l shoulder 'in'the sleeve and 'the inner face of the outer enlarged end of said valve member and effective to normally close said valve.
